Additional information

For risk assessment of ammonium sulphate the total topic of ammonia toxicity was regarded. Species mean chronic values (SMCV), as given by U.S. EPA (1999) were considered as relevant endpoints. The lowest species mean chronic value was calculated for Lepomis macrochirus EC20 = 1.35 mg N/L and EC10 = 1.12 mg N/L = 5.29 mg/L Ammonium sulphate (Smith et al. 1984, adjusted to pH 8 and 25°C).
